To all wlzomit mag concern Be it known that 'LCnARLEs WALES, a

citizen of the United] States, residing at Nashville, in the county ofDavidson and State of lennessee, 'have invented a new and usetulImprovement in Mechanism for Converting Motion, of 'which-the followingis a specification, 'rm er'ence' being had to the ac-- conipa iyiiigdrawing.

My viii prove i'ieiit relates particularly to mechanism for convertingsimple recipro- (-atory or oscillatory motion into a motion along a pathcomprising two approximately straight lines meeting each other to'forman approximately i'iglit angle, the expression simple reciprocatory oroscillatory niolion heiiighere used as meaning movementirra straightline or in an approximately uniform curve,'\vithout angle or off-set-al')2 lCli-:ll1(l-f0ltll movement of some member" in a straight line orin a curved line-which is concentric'to a fixed axis.

The objectofnny improvement is to proride a mechanism whereby 'amechanical member having such reciprocatory or oscil latory movement onsuch a straight line, or

,oiisueh a curved line, may cause a back-andiorth movement of anothermechanical member iiian L-shape path, a path which consists of twpsubstantially straight path sectioiiswhich meet-- each other at a rightangle. The member thus moving through Slll'll L-SlHlPQ path mavbe usedpractically for various kinds of work. as, for instance,

such member may be made to move liori-'. Zuiltzllifi' beneath anothermember, and then,

li an upward iiiovennrnt. lift such other member. and then returnthrough the same path to its first position.

For convenience in description, the member ii'ulii which motion istransmitted 1S hereinafter termed the "motion transmitting member whilethe member to \vliiclr motion transmitted is termed the motion receivingmember i l L" thi'e'e positions of a member ll lhi lil member to whichmotion MECHANISM r03 GONVEBTiN G am Specification of Letters Iatent; tnt D angle or said path; Fig. 3 isa side ele- Renewedfiovemberll, 1914.Serial 10.587582 of an apparatus embodying .my ment, the motionreceiving member being a the outer end of the horizontal portion oil thepath; F ig, 4 is a similar. elevation, showing the receiving member. atthe angle of the.

Saidhinge is between the ends of the traveler, 8, so that a portion of thebody of said traveler extends outward beyond the outer end of therocking member and another portion "extends inward toward, and past, theaxis of the rocking member, thus permittingthat portion of the travelerto move toward and from the axis of the rocking member, or towardandfrom the rocking member, the rocking member and said inner portion ofthe traveler being adapted to approach and recede from each other,through a limited range, like the movement of the two blades of a pairof shears. Thus anv' point in said lower portion of vthe traveler, oranymember carried by said lower portion, may. move toward or from said axls'25 in a curve which is concentric 0 the hinge axis on which thetraveler and the rocking -member are joined to each other. But .myimproved mechanism is so organized, that during a portion of themovement of the rocking member, the traveler is carried bodily by therocking member without movement of the traveler upon its hinge, all portions of th'e trai eler' then havingonly one motion-in curves which areconcentric to 3-5 the axis of the rocking member (which is the axis ofthe shaft, D,) and that during a portion of the movement of the rockingmember, the lower portion of the traveler moves through the combinedpath resulting 40 from the bodily movement of the traveler in a curvehaving for its axis the axis of the rocking member, and at the same timeturning upon its own ax isthe hinge by which "the traveler .is joined tothe rocking me'mher. The movement of the inner end of the travelertoward the inner portion of the rocking member, by the turning of thetraveler'upon its hinge, is limited by the abutting of some portion ofthe traveler against some portion of the rocking member. In the form ofmechanism illustrated by Figs.

3, at and-5,.such an abutting occurs between the'extension, 9, of theinner portion of the travelerand the extension. 10 0f therockihglniember, The inner portion of the traveler is extended away fromthe axis of the rocking'meniher, and bears the part or portion. 11,which may be integral with the carrying member or may be detachabletherefrom. "Said portion, 11. is a convenient portion to use for theengagement of any part upon which the traveler, S, is to actor work; andsuch portion may be regarded as the wor ing portion .of the traveler. Inthe drawings, this portion, 11, isshown as a power thereto in anysuitable separate piece, in the form "of a three-sided prism resting ina V-shape notch, 12, in'the traveler, and there secured by a slide key,-13, extending into a portion of theprism. and into a portion of thetraveler. For 0011-. 'venience in description, this portion of thetraveler .is herein termed the motion receiving member while the rockingmember termed the F motion transmitting memwithin the limits thus fixed,said rockingmember may move by the application of for example, throughthe shaft. 11.-

The outer end of the traveler extends far enough to the right as shownin Figs. 3, 4 and 5), to make contact with the adjacent face of theabutment, B during the latter portion of the rightward movement of themanner, as,

rocking member. and the hinge, 7. After ,such contact, 'the place ofsuch contact (which moves downward)- serves as a shifting fulcrum, andthe entire traveler, 8,,is

carried bodily downward and at the same time turned rightward upon suchfulcrum.

This results in a rightward movement of the motion receiving member inthe portion of the path which is an approximately horizontal straightline, but which is, in fact, a curved line resulting from thesimultaneous downward movement of the hinge, 7, in

an oblique curve which is concentric to theshaft, D, and a rightwardmovement of the lower portion of the traveler bythe turning" ofsaidmember on the hinge, 7. This movement terminates when'the rockingmember abuts against the stop, 1%. Such downward movement of the motionreceiving member, 11, and the lower portion of the traveler, 8, isagainst the action of gravity, and against the action of a contractingspring 16, (if the latter 15 used). Gravity becomes a factor in thisway, because'the receiving member. 11,

and the greater portion of the mass of the traveler, 8, are at the righthand side of the hinge, 7. The receiving member, 11, is now at the limitof its rightward movement, or at the right hand end of its path, andsuch position may be designated as the first or initial position of saidmember, this being the position represented by 3 in Fig. 2. When therocking member is now moved leftward, said member carries the hinge, 7,upward and leftward, away from the abut ment, B so as to free the upperend of the traveler from engagement with said abutment, and allow saidtraveler to turn in response to gravity, the lower end of the travelergoing leftward. and the 'upperend going rightward. The said turn ngmovement of the traveler is arrested'by the abutnearly in horizontalalinement with the axis of the rocking member. 'Said upward movementceases when the rocking member makes contact with the stop, 15. Inasmuchas suclrmovement of the motion receiving member is through a portion ofthe curve concentric to theorockin'g member axis and ,s'h'ort proportionto the distance from said axis, it follows that such movement up- "wardis, for most practical purposes, a

straightll .upward movement. When the rockingmemberis again movingrightward, the receiving member, 11, moves downward in the same uprightpath in which it moved 1.upward,unti lthe upper. end of the. traveler,

8, again makes contact with the abutment,

B Thereafter, during the continuation of I the. rightward movement ofthe rocking j-member, the lower portion of-the traveler -ing member inthat direction, in the former "approximately horizontal path, until theagain reached. mg 111911011 of the rocking member (which is thetransmitting member) is converted into through the L-shape path, the twowhich path are approximately straight lines.

Tl1e iocking of the rocking member, 6, may be effected by the aid of ahorizontal ar-m,17;, rigidly secured bv one end to the rock-shaft. I),and having its other end eX- tended. between stops, 18 and 19, of thestandard; C, such stopsserring to limit the up-and-dor-rn movement of:said 7 arm. (Fi-gs..-3,..-and 5.) When such stops are used, .tliesto, lland 15, on'the standard,

Bygmaw be. omitted. It will beobserved that, on the sake of accuracy,any stops used forshlimiti-ng tlie movement of the rocking member shouldbe as far from the'a'Xis of said memberas is feasible.

' I -rl ig. 7, the arm, 17, is upright on the shaft, D. and its movementis consequently from right to leftand from left to right. And in Fig. 8,the arm, 'li'ijis made a'continuation' of the upper end or portionof'the rocking member, 6. In other words, the rocking member and saidarm are made integral, and thelatter leans righti vard, the traveler, 8,being in this case/between the only "one movement, that being in unisonagain moves rightward, carrying the receiv- I initial or first positionof said member is In thls manner the; roclra bat '-a,nd-I"orth'motionof'the receiving,

In this position, the movement of the m fi ber,
